MACHINE FOR DRYING YARN.

Specification of Letters Patent. Patented Sept. 14, 1909.

Application filed December 4, 1907. Serial No. 405,044.

To all whom it may concer/n.:

Be it known that we, THOMAS ALLsor and IVALTER W. SIBsoN, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Drying Yarn; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in machines for drying yarn, and more particularly relates to machines for drying yarn wound in conical form.

As practiced at the present time in the dyeing of yarn, the latter is wound in cone form prior to treatment by the dye, in contradistinction to dyeing the same in banks, as has usually obtained, and these cones are bodily lsubjected to the dye liquor to impregnate the yarn therewith. By reason of the fact that the layers of yarn approximate two inches, more or less, in thickness it is most diiiicult to properly dry the cones, and when dyed in delicate colors there is more or less danger of the colors fading or varying in different parts of the cones, especially if the outside layer of yarn must be baked for a great length of time in order to obtain dry yarn at the inside of the cone.

To provide a machine by which conicallywound yarn may be uniformly dried throughout the entire thickness of the cones, witnout causing the yarn either to fade, or vary in color in parts of the cones, by reason of the drying operation, is the object of the present invention, to which end the invention contemplates the provision of a machine embodying in its construction simple for properly supporting the cones during the drying operation, whereby the drying medium may freely circulate about the cones, acting upon each to the fullest measure, and serving to eifectually dry out the yarn from the center of the cone to the exterior thereof without in the least varying the shade or the color thereof. f

The invention further contemplates the provision of a machine designed to operate with the highest degree of economy, and so constructed as to accommodate a maximum number of cones for simultaneous treatment without impairing the condition of any 1ndividual cone, or causing the uniform treatment of the mass to be affected or varied.

Having these general objects in view, and others that will appear as the nature of the improvements is better understood, the invention consists substantially in the novel construction, combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings, Figure 1 is an end elevation of a drying machine constructed in accordance with, and embodying the principles of, the present invention. Fig. 2 is a transverse sectional view thereof. Fig. 3 is a side elevation of the rack for supporting the cones during the drying operation. Fig. 4 is an end elevation thereof. Fig.' 5 is a top plan view illustrating the relative arrangement of the pin rails of the supporting rack. Fig. 6 is a detail sectional view taken through one end of one of the pin rails, and illustrating the manner of connecting the same with therail support.

Referring in detail to the drawings, the numeral l'designates the casing or housing of the machine. This casing or housing is formed of any desired material suited to the purpose, and the interior thereof is divided into a drying chamber 2 and a heating chamber 3, a partition a that extends longitudinally of the casing or housing l eecting this division.

XNithin the heating chamber 3 is a bank of heating coils 5, which coils are preferably fed with steam as the heating medium, and to the accomplishment of this end an inlet 6 is connected to the top of the coils, which inlet may be connected to any suitable steam main, the lower end of the coils being provided with a drip 7 for leading from the coils water of condensation. The coils 5 are preferably arranged in the lower end of the heating chamber 3, and in order to permit convenient access to the interior of the latter doors 8 and 9 are provided.

Arranged at the upper part of the partition 4 is an opening 9', wherein a rotary fan l() is located, and said fan is arranged to blow into the upper portion of the drying chamber 2, as will presently appear. The fan 10 is carried by a shaft 11 that extends transversely of the upper portion 'of thencasjV Ving or housing 1, and the roof of the latter that -eXtends over the drying chamber 2 tis inthe -forin of an inclined deck 12, which deck serves as a delector to direct the Vblast of the fan 10 chamber 2. ofthe shaft 11 project at the exterior of the casing 1, said ends being journa-led in suitable bearings 18, a driving pulley 14: being:

carried by the shaft 11 for the application of. power thereto from any' suitablesource. yBy

arranging the bearings 13 at vthe exterior of,

the .casing or housing .1' it will Abe seen that thesebearings vare not subjected tothe actiony of the drying medium within the casing, so

Y` that 'heatingolf the bearings is reduced to Va minimum, and likewise `lire from such cause is' also prevented.v Moreover, by employing the inclined deck 12 'itfis possible Lto .use va much shorter shaft, :and from Ia constructional .standpoint this is of decided advan` tage in that .it preventsthe fan from chattering when .running at a vhigh speed, rand gives to t'he fan shaft a firm .and steady'support.

In order to .properly support .the cones of Vyann within the casing or yhousing 1 during the drying operation a -'rack l5 is employed,-

and by referring to Figs. -3 to 6, inclusive, the `construction of this .rack will .be clearly seen.V This includes a .rectangular structure formed oiia series ofbase :rails 16, preferablv fin .the .form of pipes, the ends of .the base rails 16 beingA received .by .sockets 17 yformed in ycorner -bracketsv 18.,.the sockets 17 of veach Y bracket extending .atsubstant'ially fright angles to each other order to permit the ba seV rails l.occupying the ,position .referred Vto. Each of the corner brackets 18alsohas a verticaflly-eXtendin-g socket 19 in which isfarlip 23. The lips 23 of the 'brackets at eachy ranged a vertically-extending'standard .20, and said standards 20 and .thebase rails 16 are removably xheld* within the respective sockets olf 'the corner brackets 18 through .the Vn'uediuni of set-screws or their equivalent. @n each ofthe standardsQO is' arranged a plurality of .adjustable brackets 21,"eacfliV ofV said brackets being providedwith `aneye 22, whereby the bracket is capable .of sliding upon the standard, .and ,projecting .at right angles 'to each of the `eyes 22 is an .attaching end of the rack project inwardly, and .con

nected to said lips .are supporting rails 24C,

said rails 'being in the form of angle irons. To the supporting rails 211 are yconnected the rends o" a plurality of `pin rails 25., each off said rails having a bore .26 the upper end of. which is enlarged to provide. a socket 27,'

which sockets receive the .heads of fastening bolts 28 that fit the -bores v26 and engage the lower .flanges of the rails in the latter by nuts 29.

The rails 25 are spaced :sufficiently Strom,

downwardly into the drying It will be observed 'that the ends f 24e, being secured f eachV otherto VVfreely 'cones of'yiarn,

designated by the numeral 30, and in order `that these Ycones may .be held upon thejrails cachot' the 'latter is provided-withla series each .rail-'being arranged opposite the spaces between 'the .pins of the immediately con#` tiguous'rails, so that throughout .the entireA seriesgof 'thelpin Yrails the pinsr thereof bear -a staggered relationftoeach other. -V

By arranging series ofthe `bearing.

brackets 21 upon each ofthestandafrds120 fit..

will .be seen that ,theupin*railsconstitute a` series of shelves, .and .'.by'k.referringjtoFig. it will bepnotedthatxthe railszoi"eachfshelf sov are arnanged immediately below the .spaces between the rails of gthe shelf` immediately above, `thus enablingthefdrying medium as itis forced .upon the .cones .of the respective shelves toffreelyxact uponitfhe same. g j

By the employment of the hereindescribed machine it is possible to eiiectually dry the cones without in the least aiecting the shade or varying the color of the yarn, and the samereadily accommodates a large number of cones for simultaneous treatment without impairing the condition of anyvindividual cone, or causingthe uniform treatment of the mass to be aifected or varied.
